IMPROVEMENT IN WINDOW-FRAMES.

Speeiiication forming part of Letters Patent NOT 106,634, dated August 23,1870.

'marked thereon.

Drawing.

Figure l is a front elevation of my improved window-frame, partly in section. Fig. 2 is a transverse vvertical section, and Fig. 8 :is a front elevation, partly in section, of a modifi cation of Fi g. l, showing the principle or mode of applying my improvement to a windowsash. Fig. 4 is a detached section of Fig. 2, the window-casing being partly in section.

This invention has for its obj ect to construct a window frame and sash in such a manner as to perform the double service, to answer the purpose of a window-sash fastener, and also to enable the sash to be removed at once for the purpose of cleaning, all the parts of the frame remaining in their natural position; and to this end my invention consists in constructing a window-frame with its bearing against the sash made adjustable by means of a slat resting over spiral springs, an aperture in the j amb of the frame made to register with a pivot carried upon the sash, all of which will be hereinafter'- specically designated and set forth in the following specification and claim.

Similar letters of reference represent identical parts in all of the figures.

In the annexed drawing, forming a part of this specification, A A is the windowframe; 'I B, the sash.

D is an intermediate slat, resting against spiral springs E E,.1nade of requisite strength and durability. These springs are iitted into grooves a a., as shown in Fig. l', for the purpose of keeping them in their natural andI proper position. The slat D has its bearing against one side of the sash, and to such an extent as to support it at any point within the scope of its motion.

fj represent the usual. strips or jambs,

which serve as guides for the sash. These strips have apertures j" f to correspond and register with pivots b b.

In Fig. 4 is clearly shown the manner in which the sash is depressed for the purpose of removing it by the pivots b b entering the slot j" in the window-casing.

The operation may be stated as follows: As before stated, the sash will be held at any point where left. Vhen it is desired to remove the sash it is only necessary to bring the pivots Z1 b opposite to the apertures j" j", when the sash may be pushed in against the adjustable slat D, thereby releasing the adjoining edge of the sash, when it may be removed. The slat D can be taken out by push-- ing it up and then pressing in the upper end. (See Fig. 1.)

Fig. 3 shows the manner of applying my improvement to windows already constructed. The springs are litted into the sash, which has a longitudinal groove, precisely as they are in the Window-frame, Fig. l. A slat is then placed over the springs, which slat is made oi' such a thickness as to be partially retained within the said groove, and yet project far enough to allow the necessary play upon the springs to allow the sash to be pushed in and removed.

This makes almost a noiseless-moving sash, the constant action of the springs keeping the sash and frame in perfect parallel lines, whatever result may be produced by the action of the weather.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

The combination, with the sash B B, provided with the pivots I) b, of the strips ff, provided with slotsf f', slats D D, and springs E E, substantially as shown and described.

In testimony whereof I have hereunto subscribed iny name in the presence of two attesting witnesses this 9th day ofMay, 1870.
